>The title of this post is the error message I get when running a MVC view, my model declaration is

@model IEnumerable<Mytable>

but I get the dreaded red squiggle in design mode , I don't know if this is related but I've also lost intellisense in my views I get messages like "@Html Helper does not contain a method ActionLink" and also all calls to any "@Html helpers" are "red squigglies" , all this started when Nuget updated some libraries.

Looks like all those come from the System.Web.MVC..namespace in System.Web.Mvc.dll so I'd check for that in the references. But you say 'when running' - does that mean you project compiles OK ?
